No “mod rewrite” -> Internal Server Error

Hello folks,
I´ve installed wordpress 2.0 yesterday. The installation went fine. I can enter the admin, but I can’t enter my site -> Internal Server Error !!! After a couple of hours trying I spoke to my “Host Support” and found out, that “mod rewrite” isn’t installed. I’m at Germany’s biggest hoster “Stato” with an expensive package and feel like back in the stoneage.
Is there anyway around “mod rewrite”? Thanx and a Happy New Year, Felix
